This needs to check that you're not sudoing to a superuser. Otherwise it could be a massive escalation vulnerability.

absolutely, but no one runs random code in their production environment without undertanding it right? right?

If you change the test to u.is_superuser it should be safe, shouldn't it? You can also remove the if-test from the function body by adding the condition to the filter. That makes the view function:

@user_passes_test(lambda u: u.is_superuser)
def su(request, username, redirect_url='/'):
    su_user = get_object_or_404(User, username=username, is_active=True)
    request.session[SESSION_KEY] = su_user.id
    return http.HttpResponseRedirect(redirect_url)

yes, that's the correct thing to do
